Charles and Tim Heppner Passive House in Chicago

In the fall of 2009 I visited this Passive House on the south side of Chicago, Illinois. I didn’t really know much about Passive houses at the time, but I was impressed by one thing in particular. The homeowner opened a window on the first floor and there was no rush of cold air. In fact there was no perceptible air movement at all. This was because The house is very “tight” The air didn’t rush in because there wasn’t anywhere for it to go. I won’t go rambling on about what a passive house is here. Follow the link to my article on the topic, or just Google “passive house” or passivhaus.”
